Cxcl12a knockdown places the Cxcl12/Cxcr4 signalling axis downstream of miR-206.
(A) Whole body neutrophil counts at 3 dpi of cxcl12a and double (cxcl12a and miR-206) knockdown embryos. (B) Measurement of neutrophil recruitment to M. marinum following trunk injection in double knockdown embryos. (C) Bacterial burden at 3 dpi in M. marinum-infected double knockdown embryos. Each data point represents a single measurement, with the mean and SEM shown. For time-lapse imaging, each data point represents the mean of 4 foci of infection from 4 separate embryos. Bacterial burden analysis was performed on 20–30 embryos per treatment. Graphs are representative of 2 biological replicates.
